I don't understand you Stefan. In fact, the Wekinator's creator, that is the father of UAna implements similar in her source code. I attach it.

Hi Fernando!

All the usages of =^ (disconnect operator) at the top of your code don't make sense. Maybe you want to replace all of those with => ?

Hi users,

I am writting a program to extract audio features but the autoCorr, xCorr always give me a 0 value. ZeroX always give me 0.5 value.

This is a brief of the source code:

//Definitions for features extraction

adc => FFT fft =^ RMS rms => blackhole;

fft =^ RollOff rolloff => blackhole;

fft =^ Centroid centroid => blackhole;

fft =^ Flux flux => blackhole;

fft =^ ZeroX zerox => blackhole;

adc => AutoCorr autoCorr => blackhole;

fft =^ XCorr xCorr => blackhole;

//Feauture extraction

fft.upchuck() @=> UAnaBlob blobFFT;

rms.upchuck() @=> UAnaBlob blobRMS;

(blobRMS.fval(0) * 100000) => volumenInst;

rolloff.upchuck() @=> UAnaBlob blobRollOff;

(blobRollOff.fval(0)*srate )/2 => rollOffInst ;

centroid.upchuck() @=> UAnaBlob blobCentroid;

(blobCentroid.fval(0)*srate)/2=> centroideInst;

flux.upchuck() @=> UAnaBlob blobFlux;

blobFlux.fval(0) => similitudInst;

zerox.upchuck() @=> UAnaBlob blobZeroX;

blobZeroX.fval(0) => zeroXInst; ///<-----------

xCorr.upchuck() @=> UAnaBlob blobxCorr;

blobxCorr.fval(0) => correlacionCruzadaInst; ///<-----------

autoCorr.upchuck() @=> UAnaBlob blobAutocorrelacion;

blobAutocorrelacion.fval(0) => autocorrelacionInst; ///<-----------

Kindy Regards.
